Django - No module named 'mywebsite'-CodePudding

I have a django app that I downloaded from a Github repo where the main app is not called "mywebsite" (like instructed in the django tutorial).

Everytime I run python manage.py runserver i get the following error.

Conceptually I understand the error, but practically I don't. The issue can't be that I have always need to name my repo "mywebsite" right?

This is the current repo structure.

ModuleNotFoundError: No module named 'mywebsite'

CodePudding user response：

Most likely it's because of your project name. You have 2 options at the moment: (1) rename back to mywebsite or (2) rename all occurences of "mywebsite" in your project to your project name.

If you so choose (2), check your project settings and you'll see lot of variables like this ROOT_URLCONF = 'mywebsite.urls' for which you have to change to ROOT_URLCONF = 'yggdrasil.urls'. And you must also do that in all your apps and everywhere else that uses mywebsite as root reference.

CodePudding user response：

I've gone through the code in the repo and apparently everything seems to be in order.

Looking then again at the error OP gets, it starts in line

mod = importlib.import_module(self.SETTINGS_MODULE)

which then searches for a file using a path different than Windows, File "/opt/homebrew/Cellar/python.... This shows that OP is having a problem importing the settings module.

After some digging, found this page in Django docs that states

If this variable isn’t set, the default wsgi.py sets it to mysite.settings, where mysite is the name of your project. That’s how runserver discovers the default settings file by default.

To fix it, try enforcing the value for in your wsgi.py file, like

os.environ["DJANGO_SETTINGS_MODULE"] = "yggdrasil.settings"
